Culex quinquefasciatus is the major vector that is dominant and widespread mosquito distributed in rural and urban areas. This study aimed at determining the diagnostic doses of LC50 and LC90 (lethal concentrations that causes 50% and 90% mortality respectively) of commonly used insecticides in Malaysia for dengue vector control by Malaysian Ministry of Health. The diagnostic LC50 of the Malathion, Pirimiphos methyl, Temephos and Deltamethrin insecticides were determined at 0.019mg/L, 0.0060 mg/L, 0.0011 mg/L and 0.0032 mg/L as well as LC90 0.033 mg/L, 0.012 mg/L, 0.0033 mg/L and 0.0010 mg/ml respectively. It is concluded that various LC50 and LC90 diagnostic doses of these insecticides were effective against the susceptible population of Cx. quinquefasciatus that also carries infective third instar larvae (L3) microfilariae. We recommend the use of these doses for effective control of Cx. quinquefasciatus population and constant monitoring of its susceptibility status will provide more information on the possible resistance that may affect the effort in the elimination of Lymphatic filariasis in affected countries.

This research was aim at evaluating the adulticidal potent against Culex mosquitoes. The results of dichloromethane extracts shows that, Cymbopogon citratus, Mentha piperita and Ocimum citriodorum contained the highest number of phytochemicals four (4) each, followed by Lamium pupureum and Zingiber officinale having three (3) the last extracts having the least phytochemicals is Senna occidantalis which contains only two (2). The results of the adulticidal bioassay of the extracts shows that Cymbopogon citratus exhibited the highest adulticidal activities against the Culex mosquitoes tested at the LC percentage mortality was recorded highest at the highest concentration by 10mg/ml (74%) and 5mg/ml (43%). The mean average mortality and standard error were also recorded at 21.7±0.47, 18.5±3.01 and 10.7±1.37 respectively. From these results, it can be concluded that, the adulticidal activity of an ext Cymbopogon citratus extract was an excellent potentials for controlling Culex mosquitoes. Therefore we recommend that it should be used to control Culex mosquito in the affected areas.

Most susceptible are children, and most commonly exposed are those who are poor and live in developing countries. Studies of children blood lead levels (BLLS) are showing cognitive impairment at increasingly lower BLLS. The sources of lead exposure vary among and within countries depending on past and current uses. Sources of lead may be from historic contamination, recycling old lead products, gold ore processing. In many countries where leaded gasoline is no longer used,average population BLLS have declined rapidly. This article highlights several major sources of lead poisoning, adverse health effects, worldwide. In addition, we recommend three primary prevention strategies for lead poisoning: Identify sources, eliminate or control sources, and monitor environmental exposures and hazards.

The DE formulations were applied at four dose rates; 250, 500, 750 and 1000 mg/kg. Bioassays were carried out at 26-34°C and at 32-45 % relative humidity (RH). Efficacy was evaluated by recording adult mortality after 7 and 14 days, and progeny production at 56 and 112 days after treatment (DAT). Adult mortality levels significantly differed among varieties, exposure periods, DE formulations and their dose rates, ranging from 27.7 to 100 %. With all DE formulations and wheat varieties, complete adult mortality was achieved at 1000 mg/kg and 14 days of exposure. SilicoSec was more effective, proving higher mortality within shorter exposure period than other formulations. Progeny production was significantly higher in untreated Cetia than in the two...

They have great potentiality to enhance soil physical properties, mineralization of nutrients, heavy metals bioavailability, and land remediation. Similarly, many studies have shown that organic matter inputs in compost or vermicompost produced in the presence of earthworms are valuable soil amendments which increased plant growth. Earthworms are now widely being use as waste mangers, composting of food and farm wastes, and soil mangers for “fertility improvement”. However, very little is known about the negative effects of earthworms in the soil ecosystem, their role in extreme environmental conditions and species of earthworms with strong resistance to heavy metals. So this paper was reviewed to explore the role of earthworm as soil and ecosystem engineer. This was already established fact but main aim of this paper is to collect the related information and conclude the future research prospects to strengthen the e...

This work reviewed the adulticidal activities of some plants extracts and oils: Lemon grass (Cymbopogon citratus), Spear mint (Mentha piperita), Lemon basil (Ocimum citriodorum), Coffee senna (Senna occidentalis), Purple dead-nettle (Lamium purpurium), and Ginger (Zingiber officinale) leaves extracted with different solvents and were established as effective bio-insecticide against different genus and species of mosquitoes which can be used as an alternative means of controlling the population of mosquito vectors that would be environmentally safe and s...

Anopheles gambiae mosquito is the vectors of Malaria disease in Tropical and Subtropical Africa, and the present practice of using synthetic pesticides to control the vector have results in the development of resistance by the mosquitoes and the pesticides causes environmental pollution and damages the ecosystem. The aim of this study was to evaluate the adulticidal activities of some plant species against Anopheles gambiae. The results of the Phytochemical analysis showed that, Anthroquinones, Soluble Steroids and Tannis are present in Jatropha curcas while Adansonia digitata possesses Saponins, Flavonoids, Anthroquinones and Tannins. C. citrates was reported to be possessing Flavonoids, Soluble starch and Tannins and was mostly reported plants to be possessing higher insecticid...

This work reviewed the adulticidal activities of some plants extracts and oils: Lemon grass (Cymbopogon citratus), Spear mint (Mentha piperita), Lemon basil (Ocimum citriodorum), Coffee senna (Senna occidentalis), Purple dead-nettle (Lamium purpurium), and Ginger (Zingiber officinale) leaves extracted with different solvents and were established as effective bio-insecticide against different genus and species of mosquitoes which can be used as an alternative means of controlling the population of mosquito vectors that would be environmentally safe and support the ecosystem. According to the established results reviewed in this work, different solvent extracts of Lemon grass (Cymbopogon citrates), Spear mint (Mentha and Coffee senna (Senna occidentalis) were observed to possess high adulticidal activities against different species of mosquitoes. Therefore, we conclude that the activities of plant extract against mosquito species depend on the solvent used in extracting the phytochemicals responsible in the responses. We recommended the use of these plants extract as bio-insecticide against mosquito vectors.

We recommended the use of these plants extract as bio-insecticide against mosquito vectors.
